2 Claims. 1

The invention relates to improvements in electric bulb removers in whicha rubber suction cup operates in conjunction with a plurality ofcontractable circular dilations located along its neck and air-escapeholes provided in its circular wall, each of said holes provided with aflexible trap-cover; and the objects of the improvement are, first, toprovide a rigid pole for the rubber cup; and, second, to afford facilityfor the proper adjustment of the cup upon an end of the said pole.

One form of the invention is illustrated in the accompanying drawings,in which Figure 1 is a vertical view of the entire tool; Figure 2, avertical view of the tool as it appears with the circular dilationshorizontally contracted under applied manual pressure; and Figure 3, adetailed cross-section view of a part of the tool on line 3, 3.

The rubber suction cup I, secured at its lower neck 2 upon end of rigidpole 3 constitutes the assembly of the entire tool. Suction faculty isprovided for the cup I when manually pressed upon the enlarged end of anelectric bulb, said manual pressure horizontally contracting thecircular dilations 4, 4, forcing air within the cup to be expelledthrough escape holes 5, 5, 5, said holes closed by the trap-covers 6, 6,6, reacting normally under external air pressure when said manualpressure is relaxed.

The cup I previously referred to, and shown in cross-section perspectivein Figure 3, is provided with a circular wall gradually increasing inthickness from a thin resilient edge or mouth continuously to a point ofmaximum increase, said point comprising that section of the neck whereinthe circular dilations 4, 4, are located; at which point the saidthickness is slightly reduced and continuously maintained along the neckto the lower neck 2 which is in communication with the pole 3, whereatthe said thickness is immediately increased, said immediate increasecontinuously maintained.

The circular dilations 4, 4, previously referred to, and also shown incross-section perspective in Figure 3, provide, through their combinedcontracted action resultant when the cup l is manually pressed upon theenlarged end of an electric light bulb (see Fig. 2), the means wherebyair within the said cup is rarefied; said means including the forcedexpulsion of air within the cup through escape holes 5, 5, 5, providedin circular wall of the said cup.

The flexible trap-covers B, 6, 6, previously referred to, provided onthe exterior surface of circular wall of cup I, and partially attachedto said wall at a point directly above escape holes 5, 5, 5, each havinga greater un-attached portion extending downward freely over the entirearea of the said holes (see Fig. 2 and Fig. 3), provide means forpreventing replacement of air expelled from within the cup (accomplishedby the manually contractable action of circular dilations 4, 4); saidmeans employing the normal reaction of the said trapcovers to externalair pressure in forcing their closure of the said holes once theupwardly applied manual pressure on the cup is relaxed, thus permittinga partial vacuum to be maintained within the cup.

I am aware that prior to my invention electric bulb removers have beenmade. I therefore do not claim such broadly; but

I claim:

1. An electric bulb remover comprising a flexible rubber suction cupmounted upon an end of a rigid pole and shaped to receive the enlargedend of an electric light bulb; said cup having a plurality ofcontractable circular shaped dilations located along its neck andairescape holes provided in its circular wall; and means provided forclosing said holes, said means including a flexible trap-cover for eachhole, said trap-covers partially attached to exterior surface ofcircular wall of said cup and each having a greater un-attached portionextending downward freely over the area of each hole exceeding in sizethe entire area of each hole.

2. An electric bulb remover comprising a rubber cup mounted upon an endof a rigid pole, said cup having a plurality of circular shapeddilations along its neck and air-escape holes in its circular wall; andmeans provided for closing said holes preventing replacement of airexpelled from within the cup when said cup is manually pressed upon theenlarged end of an electric bulb, said means including a flexibletrap-cover for each said hole, said trapcovers partially attached toouter surface of circular wall of the cup.
